Abstract

Research has been carried out to investigate the effects of microwave exposure (7 GHz, surface energy density 10-50 mW/cm2, SAR 2.1-10.5 W/kg) on learned behaviors of rats in the paradigm of conditioned avoidance reflex. It was shown that transitory reductions in conditioned behavior after acute microwave exposure occurred at an SAR equal to the intensity of rat basal metabolism. It was found cumulative effects for intermittent exposures of rats at a power density of 10 mW/cm2.

Main findings

Acute microwave exposure (7 GHz; 10–50 mW/cm2; SAR 2.1–10.5 W/kg) was associated with transitory reductions in conditioned behavior at an SAR described as equal to the intensity of rat basal metabolism. Cumulative effects were reported for intermittent exposures at a power density of 10 mW/cm2.
